Meanwhile, The Raspberry Pi User Guide, co-authored by project founder Eben Upton with Gareth Halfacree, is now out in a second edition and is a complete guide to the Raspberry Pi. It includes setup and installation information, instructions for using the Pi to power music and video, instructions for using the Pi in electronics projects, and there is a guide to networking Pi devices. Currently, it looks like the title is sold out, but there should be more copies available very shortly, as noted here.
